Kümnendnumbrite

Kümnendnumbrite, or decimal numbers, are a way of representing fractions using powers of ten. Unlike whole numbers, which represent quantities of ones, tens, hundreds, and so on, decimal numbers use a decimal point to separate the whole number part from the fractional part. Each digit to the right of the decimal point represents a progressively smaller power of ten.

The first digit to the right of the decimal point represents tenths (1/10), the second digit represents hundredths (1/100), the third represents thousandths (1/1000), and so on. For example, the number 12.345 means twelve whole units, plus three tenths, plus four hundredths, plus five thousandths. This can also be written as 12 + 3/10 + 4/100 + 5/1000.

Decimal numbers are a fundamental part of the Hindu-Arabic numeral system and are widely used in mathematics, science, engineering, and everyday life. They provide a convenient and standardized way to express and manipulate fractional quantities. Operations such as addition, subtraction, multiplication, and division can be performed on decimal numbers following specific rules to maintain accuracy. The concept of place value is crucial to understanding and working with decimal numbers.
